Ecology

3. – The natural home or environment where an organism lives.
6. – Organisms that cannot make their own food and get energy by eating other organisms.
10. – The variety of living things in a specific area or on Earth as a whole.
11. – When organisms try to use the same resources, like food, water, or space.
13. – Population growth that slows down when it reaches carrying capacity.
14. – A process in which plants use sunlight, water, and carbon dioxide to make their own food (sugar).
15. – Organisms that cannot make their own food and must eat other organisms.
17. – Non-living parts of an environment, like sunlight, temperature, water, and soil.
20. – A relationship between two species where one benefits and the other is not helped or harmed.
22. – All the different populations that live and interact in the same area.
23. – A diagram that shows how energy and matter flow from one organism to another in an ecosystem.
24. – A close relationship between two species that live together and interact closely; includes mutualism, commensalism, and parasitism.
25. – A diagram that shows the amount of energy or number of organisms at each level of a food chain.
26. – When a population grows very quickly because there are no limiting factors.

1. – A relationship between two species where both benefit.
2. – A species that has a big effect on the ecosystem; if removed, the ecosystem may change a lot.
4. – Organisms that make their own food using sunlight or chemicals, like plants or algae.
5. – An animal that eats only other animals.
7. – The ability to do work; in biology, energy comes from food and is needed by all living things.
8. – Traits that help an organism survive and reproduce in its environment.
9. – All the living and non-living things in an area and how they interact.
12. – A large region with specific climate conditions and types of plants and animals, like a desert or rainforest.
16. – The maximum number of individuals in a population that an environment can support.
18. – A process where cells break down sugar and oxygen to release energy.
19. – An animal that eats both plants and animals.
21. – Organisms like fungi and bacteria that break down dead material and return nutrients to the environment.
